If you want a formal introduction to cryptography, you should read An Introduction to Mathematical Cryptography. They also use a lot of time looking for security holes in existing protocols to make sure they can still be trusted.

In other words, we can expect the future will hold more re-engineering efforts implemented in a decidedly new manner. "We can't outguess technology evolutions." "The reality now is that we know the world won't be what we thought it would be," Hicar adds. "We don't know yet what the most important value is going to be and which will emerge in the market, so we're building for flexibility. "Our vision is that business value will be determined by how people are using our imagery to create their own business value," he says.

Instead, Graham Group recruits candidates or hires service providers according to very specific platforms, the type of project and the type of software development. "The days of the general software developer are long gone," Johnson says. Additionally, there is a purely technical organization that is home to highly specialized technical workers. Graham Group is also organizing most of its IT and business employees around various business processes. High on his list of desired skills are the ability to drive collaboration, the ability to understand business requirements and translate them into a technical format and the ability to facilitate and integrate multiple perspectives.

As the problems have become more complicated and the company has grown and there is increased specialization, we're shifting the business analyst role into the business." Now, Johnson says, "when we talk about business analysts, we're talking about embedding a portion of the IT function into the business. They would venture forth to the business, collect and interpret requirements and bring them back to IT. Traditionally, Graham Group, like many other companies, embedded business analysts in the IT organization. It's critical that business analysts have technical knowledge combined with "a very good understanding of the problem domain," Johnson says. Kim Johnson, CIO at Graham Group, a midsize construction management company based in Calgary, Alberta, says the role of business analyst is taking on greater importance at his company and others. Specifically, Capital One is seeking out professionals with business and process knowledge and agile software development skills. "The most important thing that has changed is that we need a richer mix of associates," says Alexander. Virtually all IT executives involved in re-engineering or transformation efforts list talent acquisition as a major challenge and priority. Capital One isn't alone in its need for a new and different mix of skills in its re-engineered IT organization.
